I just bought 2 100watt daylight florescent bulbs. Will these be good to flower my girl? She's already in week 3 of flowering. are these bulbs gona be ok?
The four flo's should do the job for flowering but dont use daylight balanced. Daylight balanced is best for veg'ing and something around 2500k-3500k is best for flowering. Also i'm sure you already know, but using fluorescents to flower will yield less and it wont be very compact.
Well your only real choices are fluorescents, metal haildes, and hps. As far as bulbs any warm white (2700k) bulb will do man. Your plants need something like 50w per square foot, so depending on the area of your grow room, 4 42w cfl (600w equiv) should be good until you get your hps hooked up.
